The need for a solution to inventory control
in grocery stores emerged long before a reasonable solution was found in
barcode
labels. In 1932, a student wrote a paper on a punch-card system that
would do the job that today
barcode
labels perform. The idea wasn't feasible because the punch card readers
were too bulky and too expensive unlike the
barcode
label readers stores use today.
Another student imagined using the Morse code system to assign each product
an id label, with some small changes to the Morse code symbols; the modern
barcode
labels were born. At first grocery stores were reluctant to use the new
barcode
labels since the ink was unstable and the cost of the
barcode
labels weren't cost effective for most small chains of the day. In the
early 1970s a computer company reinvented the
barcode
labels system and released it to food markets. This time around
barcode
labels were a huge success and soon became used not only in grocery
stores but also in almost all retail industries.
Companies soon began using
barcode
labels on just about every inventory item since
barcode
labels made it easier to track items in the company's possession.
Shippers could track the contents of their trucks with
barcode
labels, which dramatically lessened the time spent checking shipments in
on the loading docks. A worker could simply scan the
barcode
labels on the side of the trucks and instantly know exactly what was
being dropped off. Rental companies also use
barcode
labels to track which items are being rented and returned. Scientific
laboratories employ
barcode
labels to scan in samples while professional industries use types of
barcode
labels to keep an accurate count of inventory and assets that the
company holds. |
